Joint fixed-point self-maintenance type robot

Abstract

The invention discloses a joint fixed-point self-maintenance type robot and belongs to the field of robots. The joint fixed-point self-maintenance type robot is provided with an air supporting ball, thus when local stress of a joint is too large, a self-maintenance ball point at the joint is stressed to extrude an external force contact layer, on one hand, an outer oil bag is extruded, lubricatingoil can diffuse to the self-maintenance ball point along an oil conveying pipe, the effect of adding the lubricating oil to the position with large stress at a fixed point is achieved, therefore fixed-point lubricating self-maintenance is achieved, then abrasion is reduced, and the stability of a mechanical arm in the using process is improved. On the other hand, the outer air layer of the air supporting ball is extruded, so that a central balloon is expanded, the lubricating oil is extruded to enter the outer oil bag, and thus the lubricating oil in the outer oil bag is continuously supplemented. Compared with the prior art, the workload of supplementing lubricating oil regularly by workers is effectively reduced.

Description

technical field [0001] The invention relates to the field of robots, in particular to a fixed-point self-maintenance robot at joints. Background technique [0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. The earliest robots in history can be seen in the puppet robots built by the craftsmen ordered by Emperor Yang of the Sui Dynasty. Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in completing dangerous, heavy, and complicated tasks, improve work efficiency and quality, serve human life, and expand or extend the scope of human activities and capabilities. [0003] A robot is an automated machine. The difference is that this machine has some intelligent capabilities similar to humans or creatures, such as perception, planning, action, and coordination. It is a highly flexible automated machine. [0004] With the deepening of people's understanding of...

Problems solved by technology

[0005] During the use of the industrial robot, the mechanical arm needs to be rotated continuously, and the daily rotation frequency is extremely high, which generally leads to serious wear and tear on the joints of the robot. Therefore, the joints of the robot need to be maintained regularly. The general maintenance method is to Lubricating oil is added to the joints of the robot to slow down wear, but this method affects the use of the robot, and the staff needs to carry out a relatively large workload. There is a problem of severe local wear and tear at the joints, which leads to the gradual deterioration of the stability and accuracy of the operation of the robotic arm with the prolongation of use time
